Optical memory
Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip.
The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Calculating the costs of autonomous vehicles
The development of autonomous vehicle technology commands a lot of media coverage. Little reporting has been devoted to the costs of operating AVs, a subject that developers don’t discuss in general.
The Houston-Galveston Area Council’s website recently divulged contract figures with two startups, Drive.ai and EasyMile. For Silicon Valley-bas... » read more

Hybrid solar for hydrogen and electricity
Researchers at the Lawrence Berkeley National Laboratory developed an artificial photosynthesis solar cell capable of both storing the sun's energy as hydrogen through water splitting and outputting electricity directly.
The hybrid photoelectrochemical and voltaic (HPEV) cell gets around a limitation of other water splitting devices that shortchange... » read more

Predicting crystal structures
A group of researchers have improved a crystal structure prediction algorithm, enabling the ability to develop new crystal structures and compounds at faster rates.
In 2005, Artem Oganov, now a professor at the Skolkovo Institute of Science and Technology (Skoltech) and the Moscow Institute of Physics and Technology (MIPT), developed a crystal structure predic... » read more

Tandem solar reaches 25.2% efficiency
In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power.
Recently, two groups have reache... » read more

Atomristors for thin memory
Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip.
"For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Healing perovskites
A team from the University of Cambridge, MIT, University of Oxford, University of Bath, and Delft University of Technology discovered a way to heal defects in perovskite solar cells by exposing them to light and just the right amount of humidity.
While perovskites show promise for low-cost, efficient photovoltaics, tiny defects in the crystalline structure, called traps,... » read more

"The research paper, published in PLOS ONE, concludes that bots are more like humans than you might expect as they appear to behave differently in culturally distinct online environments. The paper says the findings are a warning to those using artificial intelligence ... » read more

Record-breaking quantum logic gate
Reaching the benchmark required theoretically to build a quantum computer, University of Oxford researchers have achieved a quantum logic gate with record-breaking 99.9% precision.
They reminded that quantum computers, which function according to the laws of quantum physics, have the potential to dwarf the processing power of today's computers, able to pro... » read more
